technical field

The invention relates to the field of rehabilitation equipment for critically ill patients, in particular to a rehabilitation device for critically ill patients.

Background technique

Severely ill patients will experience muscle atrophy due to prolonged bed rest. In order to enable the patient to eat and walk independently after the disease has slowed down; medical staff often perform passive exercise in bed first, and then lie down according to the patient's condition. Do some simple active exercises, and then you can do some bedside activities; the current bedside activities are mainly to sit on the bedside or on a chair and use a stepper to exercise the legs alone. Synchronized exercise, on the other hand, is not able to do some simple stretching. For critically ill patients, the recovery speed is relatively slow, and after monotonous steps, the muscles are sore. If proper stretching is not performed, the muscles will always be in a state of stiffness and tightening, which cannot relieve muscle fatigue and muscle elasticity. When descending, the posture of the sports body is prone to stiffness; therefore, there is currently a need for a device that can perform synchronous exercise of hands and legs and can perform stretching for exercise.

When using the present invention, firstly, the patient sits on the stool and steps on the pedals 5 on the left and right sides of the box body 2 respectively; and then uses the two hands to pull the pull rings at the ends of the front and rear ropes 7 respectively. 16. After that, you can start exercising. There are two main ways of exercising in this device. One is to alternately pull the rope 7 with both hands; at this time, the box body 2 remains motionless, and the pedals 5 keep rotating, so as to realize the synchronized exercise of hands and feet, and When exercising hands and feet, the hands and feet cooperate or resist each other. The second exercise method is: two hands pull the rope 7 at the same time, at this time the pedal 5 does not turn; the whole box 2 rises along the slide 1, so that the legs are lifted and the muscles on the legs are stretched. With one device and two operation modes, the switching of the two exercise modes can be quickly realized, and the exercise and stretching of muscles and joints can be effectively realized; no additional auxiliary tools are required.

The specific working principle is as follows:

When the two ropes 7 are pulled alternately, at this time, since the two ropes 7 are wound in opposite ways, the alternate pulling will cause the first rotating shaft 6 to reciprocate forward and reverse; at the same time, the first rotating shaft 6 drives the main shaft 4 through the reversing mechanism. The rotation of the set single direction is carried out, so the pedal 5 will always be in a state of rotation.

Specifically in the reversing mechanism, due to the existence of the left rotating shaft 8 and the right rotating shaft 9, at the same time, the first rotating shaft 6 and the left rotating shaft 8 pass through two one-way clutches in opposite directions, and cooperate with gear meshing and belt transmission. The left rotation axis 8 will always keep rotating in the forward direction; similarly, the right rotation axis 9 will always keep rotating in the reverse direction. Then, by swinging the position of the connecting plate 10 left and right, at the same time, only one of the left and right rotating shafts can drive the main shaft 4 to rotate through the intermediate shaft 22; therefore, by manually adjusting the position of the connecting plate 10, the main shaft will appear There are two opposite rotation directions, that is, the pedal 5 can rotate forward and reverse. In the specific exercise process, the medical staff or family members can pull out the positioning pin 20 after the patient has exercised for a period of time, and change the left and right swing directions of the connecting plate 10 to realize the forward and reverse direction of the pedal 5. Adjustment; so that the patient's joints can be exercised in multiple directions, which is more conducive to the recovery of the legs.

In the process of alternately pulling, for the box 2, the upper left force of the rope 7 will be mostly offset by the rotation of the first rotating shaft 6, so the box 2 receives a relatively small leftward force. 2 will be limited by the elastic pin 3 and cannot move to the left, so the box 2 can be kept at the right end of the slideway 1, that is, in the horizontal section, which is convenient for the patient to perform alternate leg exercises. In the process of exercising, a certain amount of force can be exerted on each other by the two hands, so that a certain resistance is generated during the pedaling process of the legs, which is convenient for patients to exercise actively.

If the patient's leg is injured, the hand can be used for passive training at this time, so as to realize the exercise of the foot; similarly, if the patient's hand is injured, the force can also be applied by the leg at this time, so that the hand can be trained. Do passive training.

When the two ropes 7 are pulled at the same time, because the two ropes 7 and the two ends of the first rotating shaft 6 are wound in opposite directions, the first rotating shaft 6 cannot rotate after being pulled at the same time. Under the strong leftward force of the rope 7, the box body 2 will squeeze the elastic pin 3, so that the box body 2 moves to the upper left along the slideway 1; at this time, the patient can straighten the leg and place it on the pedal 5 , for better stretching. The patient can choose the appropriate stretch length according to his body's capacity, so that the muscles of the legs can be stretched within the tolerance range; through stretching, the fatigue of the muscles can be effectively relieved and the muscles can be prevented from being in a tense state all the time. , so that the muscles can be relaxed, the joints can be exercised more substantially, and the stiffness of the muscles can be avoided.

When the rope 7 is loosened at the same time, the box 2 will descend along the slideway 1 under the action of its own weight, and return to the rightmost end of the slideway 1, and then can be stretched again. Stretch the muscles of the arms and legs, so that the patient's limb muscles can be recovered quickly.

The above is the use mode of the device when the patient is alone in active training. The device can be easily exercised passively. During passive exercise, medical staff or family members need to operate the pull rings 16 of the two ropes 7, so that the patient's legs can follow the movement. With the intervention of external force, passive training can be carried out, so that when the patient is tired from active training, family members can carry out passive exercise, so that the patient's joints can be fully moved, and the muscles can be relaxed to relieve fatigue.

When exercising with this device, patients can stretch both before and after exercise. Before exercise, stretching can prevent ankle or other joint injuries. After exercise, stretching can help muscles relax, increase muscle elasticity, and relieve fatigue. .

By setting the slideway 1 in this device, the stepper, that is, the box 2 in the device and the devices inside it can move to the upper left along the slideway 1, so that the patient's legs can be stretched to an appropriate degree. It is more conducive to the recovery of the patient, especially after a long time of walking, it can be quickly stretched to relieve the muscles of the legs.

The device controls the rotation of the pedal 5 by pulling the rope 7 alternately, realizes the synchronous exercise of the hands and the legs, can exercise the muscles of the hands and the legs at the same time, increases the coordination ability of the hands and feet, and through the convenient reversing mechanism, The forward and reverse bidirectional rotation of the pedal 5 can be realized, which is beneficial to the bidirectional exercise of the joints, facilitates faster recovery, and avoids the fatigue of muscles and joints caused by the unidirectional motion.

Through ingenious design, the device realizes the function of stepping by pulling the ropes 7 alternately. By pulling the ropes 7 at the same time, the lifting and stretching of the legs are realized. The operation is convenient and no additional stretching device is required. Small, easy to place, suitable for various environments, and can be conveniently placed beside the bed or other areas for activities.
